Long Description:
The Lafarge Dundas Quarry is comprised of three licences quarries (referred to as the South Quarry, the North Quarry and the North Quarry Extension.

The Lafarge Dundas Quarry continues to be an important contributor to the annual supply of crushed stone to support the Hamilton and broader Ontario economy. The Lafarge Dundas Quarry produces between 3.5 to 4 million tonnes of high quality crushed stone products a year. Most of this crushed stone is used in construction work in Hamilton and surrounding areas within the Greater Horseshoe, within an hour's drive of the Quarry.

A significant proportion of our product is used directly by the Hamilton steel industry, which, of course, plays a key role in the Hamilton economy.

The Lafarge Dundas Quarry operates all year long, 24 hours a day. Production typically occurs nine months out of the year. The rest of the months are typically used for maintenance work.

The Lafarge Dundas Quarry is located within the Guelph and Lockport Formations that were formed during the Silurian Period. The rock that is extracted here is classified as bituminous dolomitic limestone. The top bench is primarily the Guelph Formation and is metallurgical grade limestone prized by the steel industry. The bottom bench is primarily in the Eramosa Formation and is dolostone.

The Quarry is rich in minerals, and not so much in fossils. Most of the minerals here are found in the contact areas between the limestone and the dolostone. Minerals found at the Lafarge Dundas Quarry, as compiled by the T.J., London Gem and Mineral Club, include: Calcite, Celestite, Fluorite, Gypsum, Sphalerite, Galena, Pyrite, Marcasite, Quartz, Selenite, Strontianite, Dolomite, Chalcopyrite, Pyrrhotite, Aragonite, and Melanterite. Mineral specimens from this quarry have been on display at the Royal Ontario Museum (ROM) and the Earth Science Museum in the University of Waterloo, amongst other places.

The Lafarge Dundas Quarry places much value in being a good neighbour. Lafarge has created an initiative called “Deep Roots”, that emphasizes monetary sponsorships, in-kind donations, and volunteer hours in an effort to give back to our local communities on an annual basis.
